Making LaTeX Beamer Black & White

Question

Is there a way to make LaTeX Beamer output black & white? I need it for paper printing purposes. I'm using the default color theme, and for contrast reasons I need the title and everything to be black. If there is a black&white color scheme, I could use it, but otherwise I don't want other color schemes, with colored backgrounds. Maybe there are some commands which I can redefine?

Thanks.

Answer 1

You can also just add gray option to documentclass declaration:

\documentclass[gray]{beamer}
...

Answer 2

OK, found it after some more search. The answer is:

\setbeamercolor{frametitle}{fg=black}
